<PRE><B>Question 986022</B>
find the values of the trig functions of theta, for example sin(theta)=3/5 ? 
------
By definition, sin = y/r
So y = 3 and r = 5
----
Then x = sqrt[5^2-3^2] = 4
-----
sin = y/r = 3/5
cos = x/4 = 4/5
tan = y/x = 3/4
----
csc = r/y = 5/3
sec = r/x = 5/4
cot = x/y = 4/3
